Coating Process for High Volume Applications

Validation

  • Beginning with provided samples, HZO engineers determine the best coating solution to meet the customer’s protection and manufacturing requirements.
  • HZO engineers work with the customer to integrate their solution into the product’s manufacturing process.
  • Models include coating as a service or direct integration of HZO’s equipment and processes into the production process.
hzo-consumer-electronics-validation-01

Pre-Production

  • Pre-processing begins with inspection for quality standards and control for product tracking.
  • When required, masking of areas where protection is not needed can be manual or fully automated.
  • High-speed equipment applies masking materials to pre-determined areas of the product’s substrate.
hzo-consumer-electronics-pre-production-01

Production

  • The products to be coated are placed inside large HZO coating chambers with a unique cube-shaped design to optimize component throughput.
  • The chemical vapor deposition process begins as the raw material is sublimated into a vapor phase.
  • After pyrolysis, the vapor flows into the vacuum chamber where it is deposited at a low temperature, forming a uniform, nano to microns-thin coating.
  • Typically coating at two times faster throughput than the industry average, the coated components are removed and placed into post-production.
hzo-consumer-electronics-production-01

Post-Production

  • After coating, any masking materials are removed with complex accuracy and dexterity, either manually or automated.
  • Laser scoring, ablation, and automated inspection can help mitigate touchpoints.
  • Each product is optically inspected for quality before being sent out.
  • The components are passed along to the next stage in production.
hzo-consumer-electronics-post-production-01

Cost

  • IP (intellectual portfolio) backed masking automation reduces labor and costs
  • Automate, Semi-automate, and Manual Masking Available
  • Rework expertise

Quality

Millions of components coated, no product returns attributed to coating issues
